From the episode in which Michael, with the backing of the corporation modeled after 3M(run by Paul Dooley), was looking to buy out DAA from underneath Miles, one of the “As” was deceased and his widow, Carol, controlled his shares and the other “A” had moved to California and become some type of New Age Shaman.

Bert Cooper and Partners. That is, if Bert wants any part of this, which he might not. Otherwise it’s gonna sound kind of like this jokey band name I made up as a kid: Earth, Blood, Wind, Sweat, Fire and Tears. Too many names. And Bert is the one guy they’d all agree to defer to, because of seniority.

But if they wanted to be more cutting edge sounding, they could be one of the first agencies with a non-partner name, like Young Ideas or Ad Infinitum.

I love the idea of having Don advance something forward-thinking and connected to recent imagery of the future, like:

Stratosphere Partners

or some address of a yet to be secured new office for them, along the lines of:

500 Madison

But smart people keep reminding me that in 1968, with the exception of Pushpin Studios, naming an ad agency after anything other than the partners simply wasn’t done. So, wild hare predictions: Harry’s going to find a way to get his name in. Bert’s out. It will take a named partnership to keep Peggy there and they can’t live without her. Gleason’s condition won’t delay Cutler’s retirement for long, so they won’t want either of those names. Pete is not leaving; he will be a festering wound that will destroy the beast from within. And Sterling dies before they get the business cards printed.

Better to select a descriptive of services name, but even that can be a problem as times change ( e.g Buggywhips R US
